What is ERW Tube Mill

High Frequency ERW Tube Mill is used for producing straight seam welded steel tubes and pipes, it occupies a decisive position in the field of industry and building pipe. ERW (Electric Resistance Welding) is a kind of welding method which uses resistance heat as energy source. Regarding its classification, ERW tubes can be roughly divided into 2 forms of ERW AC welding steel pipes and ERW DC welded steel pipes. And according to a different frequency, ERW seam-welded tubes can also be classified into low-frequency welding, medium frequency welding pipes, and supercurrent welding pipes.

High-Frequency welded pipe machines are widely used in building structures, oil and gas transportation, electric power, chemical, convey and other industries. Industry material is a very high requirement for pipe manufacturing quality, so how to select a group of excellent pipes making machine is particularly important.

The high-frequency welded pipe machine is to feed a steel strip of a certain specification into the machine, curl the steel strip into a tube billet through the forming roller, and then use the high-frequency proximity effect and skin effect to quickly heat the pipe edge to the welding temperature, and then press the extrusion roller The welding is completed under the extrusion force, and then the steel pipe of the required specification is cooled, sized, and roughly straightened.
